Fix skipped backups caused by lock file collisions and prevent overlapping jobs.
Runtime
Plugin Dependencies
Use this checklist to validate plugin runtime health before provider setup and backup execution.
Migrations

Cloud Provider Access Policy
Provider access differs by plan and entitlement mapping; this page clarifies policy boundaries.
Operations Policy
On-Demand Backup Policy
On-demand backups are policy-governed to balance operator flexibility and system stability.
Migrations
Migration Policy Reference
Before migrating, validate slot entitlement, source package readiness, and destination pre-flight health.
Migrations
Source-Destination Port Reachability FAIL
Resolve endpoint and port mapping issues before rerunning migration pre-flight checks.
Migrations
Destination Unzip FAIL
Install and validate unzip support on destination host before migration apply.
Migrations
Destination DB Connection FAIL
Validate destination database host/user/password and destination-to-DB network path.
